sex

First I wondered where children came from.
Then I wondered what was happening to me at night.
Then I found out, it could give pleasure.
Later I discovered that the pleasure was lonely and short lived.
Still later, I found out it could be shared and bring us closer.
After that I discovered that it could hurt and maim.
Then I found that it could bring children.
Having closed the circle, finally, I find that I can live without it.
